Hi,

My table has two columns amount and amountEstimated.

I would like to get a sum of the money using following logic.

If (amount == null) use amountEstimated
Else use amount.

How do I write a SQL for this?

Thanks so much for your help

That depends on what database you are using. Here is a page which gives examples for a couple of the more common databases.
